Varicose veins of lower limbs, commonly known as “old rotten legs”, is a common disease, the onset of which is mostly related to poor venous blood flow in the lower limbs due to prolonged standing and walking, and venous stasis in the lower limbs. In the early stage, varicose veins of lower limbs can cause lower limbs soreness, weakness, calf swelling, red or blue color like spider webs, twisted blood vessels of earthworms or hard nodules like tree tumors on the skin of lower limbs; in the later stage, skin pigmentation appears and eventually skin ulcers are formed, which are hard to heal and become “old rotten legs” and seriously affect the quality of life of patients. The treatment of varicose veins in lower extremities should be done with the help of a doctor. The treatment of varicose veins of lower limbs should take systematic treatment methods, including general treatment, drug treatment and surgery. We should not rely solely on surgical treatment and neglect systemic treatment, which leads to relapse in some patients. In the early stage of the disease or after the surgical treatment, how should the patients themselves perform self-care to relieve the symptoms, slow down the progress of the disease, or prevent the disease from recurring? The following measures can be taken by those who suffer from this disease, mainly including: 1, appropriate exercise, avoid prolonged standing, walking and weight-bearing; 2, wear medical elastic stockings when working and moving outside; 3, elevate the lower limbs when resting, such as raising the bed leg 10-20cm, or using a soft pillow to elevate the lower leg 10-20cm; 4, the water should not be too hot when bathing the legs, and avoid taking sauna baths; 5, sitting time More than 1 hour, appropriate exercises such as tiptoeing to promote blood return to the lower limbs; 6, drink more water appropriately to avoid blood concentration; 7, after surgical treatment should still protect the affected limbs and avoid prolonged standing or sitting. Change your posture frequently to promote blood flow, obese patients should lose weight and insist on wearing medical elastic stockings to reduce the recurrence of varicose veins in lower limbs.
